Science: Safe Gas

At West Babylon, N. Y., experimenters announced the development of a
new illuminating gas. The raw material used: crude oil or refinery
residuum. The product: a hydrogen and carbon combination containing
no carbon monoxide because manufactured at low temperatures. The
product's qualities : non-asphyxiating because void of carbon
monoxide ; content of 1,600 British thermal (heat) units as against
525 to 585 units in most illuminating gases. From 7 gal. of refinery
residuum are produced 1,000 cu. ft. of the new gas and a by-product of
1½ gal. of gasoline high in...
